<prompt> Human: Based on the 10 year Shiller PE Im thinking of stopping new investments or maybe selling.Assistant: Which market? International holdings underperformed the sp for years. If youve got a diversified portfolio, you should be doing fine.Besides, people with your attitude miss huge growth. Shiller cant predict market movement on a short term.Human: SP 500  <response>: And? Shiller incorrectly called tops in 2013 amd 2014. Your post is really nothing more than questioning the effectiveness of market timing, which doesnt work.
