We tipped shares in the coal-fired generator a fortnight ago because of its generous dividend policy, but saw prospects transformed last week when the UK government agreed to help finance a switch to biomass production - burning woodchips, in layman's language.
Recent buyers believe benefits from the switch means it is now only a matter of time before Drax receives a takeover bid from one of the Big Six energy companies and its share price responded with a rise of more than 10% over the week.
Scots transport giant Stagecoach was another tip to move against the general trend, with a useful rise after directors announced a hefty dividend rise. And Smiths Industries gained ground on gossip about a potential offer for its medical supplies operation.
The 2012 portfolio was the main beneficiary, with its value increasing almost 3% over a week when most leading shares had drifted lower on concerns about a cutback in the American stimulus programme.
The 2013 selections also managed a small rise, helped by further support for Dunfermline-based retinal imaging group Optos after its recent trading statement, as well as the Stagecoach gain. But profit-taking in shares of Greenock's British Polythene Industries contributed to a 0.8% slippage in the value of the 2011 portfolio.
The 2010 portfolio - due to be liquidated at the end of the month - recorded a similar fall after publishing group Pearson was hit by concerns over its major US interests and is now only fractionally above our 100% appreciation target. But we still expect to hold on to the double-your-money figure.
