Looking for good investment vehicle for seasonal work and savings
Most online "high yield" savings accounts are paying just above 1%.  That would be 1.05% for American Express personal savings, or 1.15% for Synchrony Bank‎ (currently). Depending on the length of the season, you might want to work in some CD's.  Six months CDs can be had at 1.2%, and 9 month at 1.25%.  So if you know you won't need some of your earnings for 9 months, you could earn 1.25% on your money. However, I would proceed with caution on anything other than the high yield savings account.  With your one friend having such a low emergency fund, there is very little room for error.  Perhaps until that amount is built up into something significant, it is just best to stick with the online savings. Of course, one solution would be to find a way to create income during the off season.  That will go a long way into helping one build wealth.
