The pretax margin of Alpha and Omega Semiconductor Ltd has fluctuated significantly over the past several quarters, indicating some variability in the company's profitability before accounting for taxes.

The pretax margin was negative in the most recent quarter at -1.13%, showing that the company experienced a pre-tax loss relative to its revenue. This was a decline from the previous quarter where the pretax margin was also negative at -0.98%.

Looking back further, the company showed a downward trend in pretax margin, with negative pretax margins in the past four quarters. However, in the quarter before that, there was a sharp increase in pretax margin to 2.64%, followed by a strong performance of 4.84% in the quarter prior. This suggests that there may have been certain factors contributing to the higher profitability in those quarters that were not sustained in the subsequent quarters.

Overall, the pretax margin trend indicates some instability in the company's ability to generate profits before tax, with recent quarters showing negative margins. This could be a concern for investors and stakeholders as they assess the company's financial health and performance.
