In the case of NVDA, as I shared last week, i did this in 2 steps
Step 1: Buy put spread 140:125 (1:1) when NVDA is around 140. This essentially protects the drop until 125 by paying for some premium
Step 2: Wait for NVDA to drop to 132-135 area and add 2nd leg of put (ie, selling more 125 put). The idea is to use this second leg to collect credit to compensate the pemium paid in Step 1
Net net, you will get a 140:125 (1:2) ratio put spread, with almost 0 cost.
Also, since I expect NVDA is likely to trade below 160, I also opened a 140-150 ratio call spread (1:2), this allows for capturing the NVDA upside as long as it does not go above 160
