If you have 0 NVDA shares, you could consider buying 1/3 position around 115, as NVDA could drop to 108 if the current weakness continues, by which time you could buy another 1/3. But then again, it may just hold 115. No one can tell you where NVDA will go in short term
If you already have NVDA shares and want to add more, best to wait and see whether NVDA breaks higher or lower from here.
