Nairametrics| Whilst there is no sure way to determining when to buy and sell stocks several ideas and methodologies used by reputable investors all over the world can come in handy. The method you use of course depends on whether you are a value or growth investor as well as your investment principle

When to buy stocks

  1. Some investors like to buy stocks when the companies release ground breaking products that are strong enough to change the way people consume competing products or basically change the way consume. Companies like this always show a knack to be on top for years which often translate to higher share prices.
  2. A buy sign will lit up for some investors when a company releases periodic results that have double-digit revenue and earnings growth. For example, a company that continues to grow revenues at a rate of above ten percent compounded annual growth rate is a strong candidate for a buy. The idea is that such companies even when they initially declare losses will at the end stabilize operational cost with increasing revenues soon turning them into giant profit and cash making machines.
  3. Warren Buffet famously buys stocks when the share price is trading below its intrinsic values. An intrinsic value of a stock is basically the true value investors place on a stock. Whilst what makes up an intrinsic values is varying and often subjective, the bottom line is to buy stocks when it is trading below what you perceive to be its true value in the hope that soon other investors will realize and then presenting you with an upside when the price increases.
  4. A stock trading below its book value may also be a strong candidate for a buy. However, this may be risky as stocks that trade below their book values could be for a number of negative reasons. But when a stock is trading below its book value and still records profit and revenue growth it may just be a sign that the stock is undervalued and overlooked for reasons other than its fundamentals.
  5. Investors also like stocks that pay a constant dividend. They place a premium on these stocks on an average for the dividend paid. It is therefore more likely that a dividend paying stock that increases year on year will generate growth in its value.
  6. Investors also like to place emphasis on stocks that are both market leaders in their sectors. It is however important to focus on stocks that not only lead in terms of market capitalization but on revenue and profitability share.
  7. A good time to buy may also be when prices are going up and volume is increasing. It is a method often used by market speculators as they opine prices will continue to rise.

When to sell stocks

  1. A sell mandate is often flashed when a company declares results that is below investor expectations. However, it is also important to review the results to establish if the drop is a one-off event. A drop in earnings growth for consecutive quarters for example is a sign of a stock losing market share which may soon translate to loss in value.
  2. You may also consider selling a stock when the share performance falls below your expectation. A good investor should be guided by an investing philosophy which also includes expectation on a stock’s value appreciation over time.
  3. For those investing as speculators a good time to sell a stock is also when the stock has attained a new high. Of course emotions can play here as some like to wait to see if the prices will even grow higher. Whatever the case, be guided by your investing principle rather than your emotions.
  4. Some investors also like to sell stocks when its fallen share price hits a stop-loss price. You can for example say to yourself that a stock that falls in value below twenty percent will be sold in order to minimize your losses. This again depends on your investment principle.
  5. If there are better yielding investments out there then a sell may appear feasible. For example, in a long bearish market, investors typically move their funds to other better yielding investments such as bonds and treasury bills.
  6. You can also sell stocks if you believe there are other better performing stocks than the one you have.
  7. Crisis in the management of a company or heavy regulatory squabbles may also be a good sign to sell stocks. For example, a company that has admitted to have perpetuated a huge financial fraud that might affect the authenticity of past results is mostly a candidate for a sell. More often than not such companies never recover.
  8. A good time to sell may also be when prices are going up and volume is reducing. It is a method often used by market speculators. They believe it’s an indication that prices may either increase at a slow rate or start dropping indicating a bearish market.
  9. Also when prices are falling and volume is increasing it may mean more people are dumping the shares indicating bearish market.

Finally, the tips above are not full proof for success and should be taken with the utmost caution. It should not be relied upon solely for your investment decisions.

  1. #3 on When to Sell list is incorrect. – Stocks that make new highs tend to make even newer highs and should be bought. What you described there is a contrarian trade, which could be devastating in an up-trend market.

  2. Buying and selling shares involves at least 5 factors before you buy or sell any shares ,which will go this way (1) national budget,gnp ,balance of trade,the supply of money in the national economy,statement of designated govt official,i.e cbn,ministry of finance.THIS IS GOVT PART.the nex part of yourself in picking this particular share,it also requires when to make a spontenous decision.i.e are you going for long term investment or short term investment.i.e buying spontenous selling short,which means you want cash liquidity,you buying or selling requires to trade for a few mins,for a few hours,for a few day.this pattern of trading happens mostly in forex trading,as the market moves daily.
    You can uses this spontenous in buying company’s share,but I do understand the nse have banned selling short recently.why are they do this now ?it is we do not have a robust and broadly-based stock market to absorbes when there is massive selling of share.,asset management,trust fund,specialized fund.pension fund told their percentage of share for months and years.also secondly, we do not a big figures in listed on Nigeria stock.
    However it is not possible to do justice in the mechanism of buying or selling share be done in one pages of nairametric,some specialist fund,e.g stockbrokers do employs analyst, which do for their client,and leave the decision of buying and selling share fully on the their shoulder,as they may incurs liability for giving such advices

  3. As nairametric is not paying enough dollar or non,i will be brief.now is nairametric sleeping on their job 12.28~ /15/05/2017 lagos time,the nse have surged to 26000.and they have not told us any thing,the biggest surge for 9 month,do we read it on bloogshit or cnn.
    We have two types of broad money market instrument (1) the closed instrument (2) the open instrument.The closed instrument are mutual fund,hedge funds,asset management.pension fund.Why closed instrument ?because you have to trust them with your money,you give them about 5000 naira,the decision making in investment is their not yours.if they make the right decision and makes profit ,good luck to you and them.this is the pattern that operate mostly in Nigeria.maybe this perceived globalization or not ? some Nigerian have started to by-pass this Nigeria system by using foreign broker.
    This is the open instrument or call it open system.you do your analysis or researches,you can ignore your broker’s researches.in most case of open system,your broker charges a norminal fee per a dealing.you makes all your decision,you sells and buys through your broker account number.in most case,you broker supplied you some charts,some recent new report,if you are happy with your profit,your broker is happy.in some case,some broker do not charges any fee,they get their fee by attaching pig-backing profit on your profit.
