In this article, we will look at the 8 Most Undervalued Biotech Stocks to Buy Right Now.

On April 13, Tom Lee, Fundstrat’s head of research, appeared on CNBC’s ‘Power Lunch’ to talk about his outlook on equities, what to expect in a wartime economy, and more. He said that the stocks are holding up because the economy is actually doing better in the face of this war. While this sounds counterintuitive, the defense spending going from $30 billion a month to probably $60 billion a month is quite stimulative for the economy. The $20 rise in oil is also only adding around $12 billion a month to the household burden, and therefore, on a net basis, the war is helping earnings right now, according to Lee.

He further stated that while nobody wants the US to be in a war, and right now it is caught in a fog of war, one of the things we have to remember is that going back to WWII, the stock market bottomed in May 1942, five months after the US entered the war but before any US troops were even on the ground, either in the Pacific or Europe. Therefore, according to Lee, the market does have a really good way of discounting outcomes, and he thinks the reason it is going up is that we are going to end up with a favorable outcome.

With these broader market trends in view, let’s look at the most undervalued biotech stocks to buy right now.
