<prompt> Human: Looking to start some very basic investing low fee index funds, maybe some bonds. I noticed the market is up quite high atm though and know that general rule of thumb is buy low, sell high... I know its just index funds but still dont like the idea of buying in when the market is so high. Any thoughts?  <response>: Since 1900 the market has been quite often at an all time high. If you avoided buying when it was at an all time high you would have missed decades of growth.
