I added to $PayPal (PYPL.US)$ and $SoFi Technologies (SOFI.US)$ on the down market this morning.

This got me thinking -- when you add to stocks that are down recently (almost everything for me lately), which time frame do you like to look at?

For example, DigitalOcean was down 15%+ just today on no major news. I love adding on one-day drops like these, provided nothing really changed for my investment thesis.

But I also added to PayPal and SoFi, which have been two of my worst performers over the last six months -- down 60% and 55%, respectively.
