How to do non-speculative trading?

a small Tip can make your trades a great impact

Suppose you select a good stock and long an Ethereum worth 100$ in futures

then

you hedge with a bad stock and take a short call on that stock with 100$

Now what happens?

if the market moves in a positive direction

Ethereum moves to the long side and gets a profit of suppose 120$ where you get 20$ profit

the other bad stock also moves in a positive direction and gets a loss of 90$ where you get a loss of 10$

so your profit will be 20$ - 10$ = 10$

opposite side also vice versa
