Options provide leverage. ITM options have less of it and OTM options have more of it.
Here's an assignment on how to see it. You have $1,000. Set up a spreadsheet with the the strike prices and premium cost of your six options. Determine how many calls that you can buy at each strike price (fractional contracts are allowed in this exercise because you want to compare an equi-dollar investment in each position). Then determine the P&L of each position at various expiration prices.
For example, the $27 call costs $2.50 so you'll buy 4 contracts. Break even is $29.50. At $30 it has a profit of $200 (4 x $0.50) and at $31 a profit of $600 (4 x $1.50).
Let's say that UBER will rise to at least $30. What you will find out is that at $30, the three calls with the lowest strikes will make money and the two highest will lose the entire $1,000. However, somewhere around $32.50, the 3 highest strikes will each make more than any of the lower strike positions. The higher UBER goes, the greater the multiplicative effect.
The short answer?
- Lower call strikes have a higher probability of making a small gain and lower probability of losing it all.
- Higher call strikes have a lower probability of making a large gain and higher probability of losing it all.
Approaching this on an equi-dollar speculation magnifies the effect.
