Reasonable Expectations
Reasonable expectations are a form of risk control. If the expected return is too high, too smooth, or too dependable relative to the risk being taken, investors are likely to accept hidden danger.
What Marks Means
Marks argues that every investment effort should begin with explicit, realistic expectations:
- What return is being sought?
- What risk is actually being borne?
- How much liquidity is needed?
- How does this compare with alternatives?
- What must be true for the result to happen?
Unreasonable expectations push people toward leverage, illiquidity, weak due diligence, and suspension of disbelief.
Why This Fuels Bubbles
This is not just an individual forecasting error. When many investors demand high returns with low visible pain, markets start manufacturing products and stories that pretend to offer exactly that combination. In that sense unreasonable expectations are one of the fuels of both bubble-detection and easy-credit excess.
The Basic Test
If an opportunity offers high return, low volatility, and strong dependability all at once, Marks' instinct is skepticism. What real mechanism explains that? Cheap purchase price? Rare skill? Genuine risk bearing? Leverage? Luck? If no mechanism explains the offer, then the investor is probably being paid with illusion.
