If you are invested in 50 companies, you might as well invest in a low-cost index fund which tracks the S&P 500. 50 companies (depending on their sectors) is going to probably keep you close to market return. You have the same systematic risk. Diversification is BS.
The odds are not in your favor as even 77% of mutual funds do not outperfom the S&P 500.
What you are asking do here is gamble. You will have better luck investing in 5 to 10 companies where you are taking on more risk to ourperform the S&P (the S&P will, for sure, not return that % in that time frame). You will be trading systematic risk for unsystematic risk of course (you can't escape risk altogether obviously).
Another alternative bet will be Bitcoin, Etheruem or Ripple.

Over 5-year period 77.97% of mutual funds underperformed the S&P 500. If most of these market wizards can't outperform the S&P 500, then it isn't looking good for you.

"To beat the market, you have to be different than the market. One simple way to do this is to hold a small number of stocks." (this does not guarantee you will beat market, but you will have a better chance with a portfolio of 15 or less than a portfolio of 50). I have returned over 75% in the last 1.5 years with equities, not including cryptoassets.
The bottom line is... if you aren't willing to read annual reports (like I have) and perform due diligence on specific firms, then you shouldn't be holding individual stocks. You should be invested in a low-cost index fund that tracks the market. What you are doing is pure gambling. What I do is invest in high-quality businesses at what I determine may be a fair price and don't plan on selling until they may become overvalued.
