As to when the market will peak and turn indicators down, we don’t know. Unfortunately, no one else knows either. The best that can be done is to be “situationally aware” and make a judgment about how much risk you are willing to take. That judgment thus must be left up to the reader and in some cases, the financial advisor the reader may be consulting with.
When you read any kind of advisory material, remember the author has no information about your personal financial situation. About all a general writer on markets can do, is describe conditions in the market. You are ultimately responsible for what you do with the information and whom you hire for advice.
