Look at Celsion, who tried to develop a liver cancer cure. I am an investor in 2014 when the shares are $40, I am not so happy right now with the shares at $1.75. It gets much much worse as you go back in time because of reverse splits, the shares were once hundreds of dollars.
I am SUPER unconvinced about the "risks" to investors in healthcare/pharma companies based on share prices. We can't forget that unless you're handing your money to Clesion directly, you're not investing in their company. You're buying a share of future profits from another guy. IPOs and new stock offerings can raise cash for a company, but that is a tiny tiny fraction of their total stock sales. Shares can trade hands a thousand times at a thousand different prices without raising one cent for the company.
So did you invest in Celsion directly, or did you buy shares from someone else long after the stock was issued? Share prices for stocks are loosely based on the expectation of future profit distributions, and if the company's future starts to look gloomy those expectations drop along with the share price. That's purely a function of the market, and has virtually nothing to do with what industry we're talking about.
You can totally lose money on individual stocks. Any individual stock. But whether your make a profit or loss on your purchase is determined by what other people will pay you for your share of future profits, not whether or not the company's miracle drug turns out to be a fraud. They're not unrelated, but you seem to be saying that you personally funded this drug, and then you personally took a loss because the drug didn't work out. I would argue that you were uninvolved in the drug-funding process as anything other than a secondary bystander trying to speculate on the company's broader future, and your speculation didn't pay off in this case just like it didn't for thousands of other companies you could have bought.
