Coefficient Capital co-founder Franklin Isacson describes himself as a cautious investor, especially in times of uncertainty like today. That comes in handy during a time of crisis.

For Isacson, this has been a good time particularly to invest in certain companies, especially in grocery and consumer goods that can weather a recession.

"The new funds that are being deployed over the next 24, 36 months are likely to be very good vintages, much like the '09 and '10 funds were excellent vintages," Isacson said on the Modern Retail Podcast.

Isacson lists four big lessons derived from 2008: rethinking how demand will be impacted ("consumers are going to trade down to private label during times like this"); creating backup in supply chains given the possibility of supplier bankruptcy; honesty in leadership about the uncertain times ahead; and liquidity. "Private capital markets are not always going to be there to fund your business even though you as a business might be doing well. Or even if they are, the terms just might not be as attractive," Isacson said.
