Sharpe vs Treynor ratio

A
  1. Sharpe divides excess return by total risk (standard deviation).
    Treynor divides excess return by systematic risk (beta)
  2. Sharpe is appropriate when the fund evaluated is 100pc of investor’s total investments. Treynor is appropriate when investor allocates across a number of investments. Each investment is evaluated according to individual contribution to risk and return.

Q

Market timing

  • define
  • describe charts
A

Define market timing: in pure form, involved shifting funds between market index portfolio and risk free rate.

Chart:

  1. If weight of market is constant, portfolio beta will also be constant and the SCL will be a straight line measured on (rp-rf) vs (rm-rf) space
  2. If bull and bear markets can be predicted, investor shifts more into the market when market is expected to perform. Chart will be ever increasing slope
  3. Line could also be kinked, representing beta taking on only 2 values, a large one if market expected to do well and a small one if not so well.
