The Globe and Mail reports in its Tuesday edition that Big Tech suffered a substantial wobble and repricing in the first quarter, but has roared back in the past three weeks, with market conviction in the artificial-intelligence productivity boom seemingly stronger than ever. Guest columnist Jamie McGeever writes that investors will get a sense of whether this optimism is justified this week, with Tesla, the first of the Magnificent Seven megacaps to report, releasing first-quarter results on Wednesday. IBM and Intel also report this week. Markets are clearly expecting more good news. U.S. stocks have shrugged off the Iran war and the energy supply shock to hit new all-time highs. The Nasdaq on Friday clocked its 13th daily gain, its longest winning streak since 1992, rising nearly 20 per cent in the process. Should the rally extend through Monday, it will be the best run since June, 1987. However, with global energy prices up the most in five years, there are worries that the hyperbullish earnings outlook for Big Tech -- now a highly energy-intensive sector -- could sour. If the capex numbers get pulled back, if in fact energy prices are not reflected in earnings, that could be a catalyst for an equity market pullback.
