If the sales and earnings go up in the long run, and the stocks aren’t super overvalued, then the stocks go up. It doesn’t matter what other people think. All that matters is the performance and valuation.
The price of a share is determined by exactly one thing, how much people are willing to buy them vs. willing to sell them.
If the market believes a certain stock will outperform the average it is free money to buy that stock, so prices will rice exactly to the point at which the market believes the share will not outperform the market at that price.
This is literally basic economics. Google "efficient markets".
You can see the price for yourself though vs the fundamentals and judge whether it’s a fair deal. The market isn’t omniscient and has been mispriced very frequently.
