Abstract
In response to the need for a simple financial instrument that enables retail investors to participate easily and quickly in the U.S. equity market and that facilitates basket trading by institutions, the American Stock Exchange introduced Standard and Poor’s Depository Receipts (SPDRs) on January 29, 1993. The purpose of this study is to determine the effects of the introduction of SPDRs on the pricing efficiency of the S&P futures market. Using a measure of efficiency that is based on the difference between the observed futures price and the theoretical futures price based on the Cost of Carry Model, as well as daily and intradaily data for the period January 2, 1990 through June 3, 1996, we found that some positive mispricing was reduced when SPDR’s were introduced. While dividend yield and time-to-maturity biases remained, SPDRs trading was shown to mitigate the extent of pricing errors that prevailed, and reduced the effects of dividend yield and time-to-maturity biases found for these contracts. © 2000 John Wiley & Sons, Inc.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
