Executive Summary

This section provides a brief overview of the key arguments. You do not need to read the full detailed report below.

✅ Key PRO arguments:

  1. ■The S&P 500's recovery trajectory from the March 2009 trough of 676.53 brought it to 1,426.19 by year-end 2012, a gain of over 110% from the crisis low; the December 2007 peak closing level was 1,468.36, and the index stood at 97.1% of that level.
  2. ■The opposing side relies on a hidden auxiliary assumption that 'the S&P 500' means the price index unadjusted for dividends and that the December 2007 level means the single-day closing price of 2007-12-31; the claim can be read through other December 2007 reference points or total return measures.

❌ Key ANTI arguments:

  1. ■The claim refers to the standard S&P 500 price index, which closed at 1,426.19 on 2012-12-31, strictly below the December 2007 peak closing level of 1,468.36; substituting the Total Return Index changes the claim as stated.
  2. ■The affirmative's total return argument is internally inconsistent: it first cited a total return level of 1,710.69 at end-2012 versus approximately 1,487 in December 2007, then claimed the December 2007 reference point is unstable; this creates a fatal logical gap.

💭 Conclusion: False — the S&P 500 had not recovered to its December 2007 level by 2012-12-31. The winning side showed that the claim refers to the standard S&P 500 price index, which closed at 1,426.19 on 2012-12-31, below the December 2007 peak closing level of 1,468.36. The affirmative's attempt to substitute the Total Return Index or alternative December 2007 reference points equivocates on the claim as stated. The affirmative itself conceded the price index remained below the 2007 closing level. Therefore the assertion is false.
