Don't focus on the fluctuating stock prices. If drop, consider it an opportunity to acquire more. Invest in the Start company's value, not just its stock value.

The following is from Quora by Ian Duncan MacDonald:

“A share’s price on the stock market at this moment is only remotely connected to a company’s profitable operation and its ability to pay a consistent dividend.

While the profitable operation of a company can influence a share price, today’s share prices are overwhelmingly determined by speculator bids not by the skills of those managing a financially strong companies. For a speculator to sell the shares of a company that he is sure is going to decline in value, he must first find a speculator who is sure the share price is going to rise. They both can not be right. When large volumes of shares are being traded, millions of speculators are placing their bets on which direction the stock price is heading. These millions of decisions are all conjecture by each investor, no one can accurately predict which way impact their bet will have upon the share price or to what degree their buy bet cancel out the sell bet of other investors.”
