Nedbank Put Warrant - Strange Behaviour ?

[tdejongh]

Warrant Code: TKGNBX
Earlier this week the warrant had value of round about 10c up to R180 value for underlying stock TELKOM, on the warrant calculator. Liquidity dried up at this point, and no active market-making was taking place. Now, with underlying at R175, the warrant calculator shows the value at less than 1c, and this continues all the way down to the low R160's. Gearing for the warrant is now 0%, time decay is 0%.
Is this behaviour due to trading platform magic, or am I unaware of one or more powers wieldable by warrant issuers ?
I have a standing policy of only trading Standard Bank warrants, and this once again proves its validity.
Can anyone please indicate what the true value of this warrant is at the current price point ?
