This US stock gained over 400% last week

The U.S. market posted a very bearish performance last week with major index posting declines of over 4%. The Dow, S&P 500 and NASDA all lost 4.6%, 5.1% and 5.6% respectively on the back of worrying U.S. inflation data, which showed an acceleration to a fresh 40-year high.

Major indexes posted their biggest weekly percentage declines since January and ended sharply lower last Friday. The U.S. Labor Department’s report showed the consumer price index (CPI) increased 1.0% last month after gaining 0.3% in April. Economists polled by Reuters had forecast the monthly CPI picking up 0.7%. Year-on-year, CPI surged 8.6%, its biggest gain since 1981 and following an 8.3% jump in May.

Although the market was down, we saw a stellar performance from Aeroclean Technologies, a NASDAQ quoted stock, that posted over 400%, starting the trading week at $2.48 to close $12.50.
