Many "experts" talk shit about systematic trend following, then write books teaching investors to:
• Diversify
• Respect price
• Follow trends
• React instead of anticipate
• Stay flexible and adapt when markets change
• Avoid deciding a market is "too high" or "too low"
• Accept that calling tops and bottoms often means missing some of the biggest moves
• Cut losses
• Let profits run
• Focus on the size of your winners, not how often you're right
• Manage risk relentlessly
