The Canadian benchmark index's charge above 15,000 on Tuesday came largely from oil and gold producers.
Over the longer term, however, the mix of winners contributing to the index have come from a slightly wider assortment of sectors.
Over the past five years, which takes into account most of the index's rebound from the devastating bear market that began in 2000, Research In Motion Ltd. has had the biggest influence on the index, rising a total of 3,363 per cent and adding 581 points to the index.
EnCana Corp. is close behind. It rose 304 per cent over the past five years and contributed 580 points to the index. Potash Corp. of Saskatchewan Inc. rose 1,337 per cent and contributed 559 points.
S&P/TSX Composite
A look at the relative performance of the Big Three compared to the S&P/TSX composite index.
The index itself has risen 8,342 points — or 124 per cent — over this period, which means that these three stocks accounted for more than 20 per cent of the gains.
In terms of percentage gains, as opposed to influence on the index, the biggest winners have generally been smaller companies.
UEX Corp., a uranium company, is at the top, with a 4,422 per cent increase. Gold Eagle Mines is second, with a 4,232 per cent increase. RIM, the only truly big company in the top five, falls to No. 3.
