Hidden gems which no one talks about ??

Hi everyone I have successfully finalized my portfolio with the sectors I was targeting and the right balance. However, I encountered issues when investing in small companies that did not live up to their promises. The main problem was that their stock prices were manipulated by market makers, short sellers, and others... Now, I really want to find a hidden gem for the long term. I’ve noticed that two companies have experienced significant success: Innodata and TSS Inc. However, I have never seen their names mentioned anywhere as stock market gems. Few of article said the price is high but that looks very bullish. I wanted to know whether these two companies are truly solid for the long term or if their rise is just euphoria or unreasonable speculation. I have also heard about Microvast and Microvision. They are much smaller, but many people talk about their huge potential (major contracts coming?). I am not a specialist, and I don’t want to fall into a bull trap or be caught in short sellers’ speculative games, waiting for a massive drop. Therefore, I would really appreciate your opinion. Thank you.
