Well many are the elements in evaluation of cheapness of a cb, so if you find the word ‘cheap’ for cb xyz in an analyst report, it seriously depends on 2 principal factors:- Valuation model used- Market factors that make it feel cheap the deal at issue.First, some analysts consider cb as a synthetic security with 2 parts, a plain bond and an equity warrant, with maturity set at bond first call date. The strike of your warrant is calculated with forward bullet price (example 90.00 bullet price) divided by the conversion ratio. Second step is multiplying warrant premium by conversion ratio. If you use historical volatility of underlying in this way when valuing the warrant (opt) part of your cb you should obtain fair value of the cb issue to be compared with real issue price. A cb is valued as cheap or attractive with issue prices lower than fair prices and there’s an opportunity of buying value. This method is although not complete in fact conversion opt extends itself till maturity and not limited at first call date. In addition there’s a separate valuation on credit risk of issuer. And value you buy in credit spread in bp on t-bonds. Remember to take into consideration ytm and rating.Second, analysts use to read performance of cb at sector level and equity market with delta for single issue although internal performance of convertibles reflects weakness or strength of equity markets, sometimes against a weak market backdrop valuation profile of cb may be deteriorated somewhat. Many global houses use to calculate weighted average premium level and corollary of weighted average premium expansion could be reduction of sensitivity of marketplace, other measure of equity sensitivity is s/iv; or Vega weighted IV. Putting a cb 2.07% cheap means that using your model theoretical value is 102.7 and if issue price is par (100) you could get a 2.07% value. Rgds,
