Financial analysis of Q2 2020 to Q1 2021 shows significant fluctuations across key metrics.  The ratio of retained earnings to revenue is decreasing, with substantial quarter-to-quarter variations.  SG&A expense ratio also exhibits a negative overall trend with large swings.  Investment efficiency, measured by retained earnings on assets, shows a negative overall trend, again with considerable volatility.  Further investigation is needed to understand the drivers of these fluctuations. Working capital and cost efficiency are also analyzed, but lack specific figures in the response.
