*************************************************************************************************** Doit3: starting new run If bankrupt, interpreting as before reported date Index = S&P500 merging all rounds together Results for information indsustry Includes Communications, Electronics, Information Serivces, Other IT, Semiconductors and software. Using round to IPO/Acquisition returns. Returns overlap for same company! Doing model with k, bankruptcy minage parameter 0.25 using all rounds, even those that take less than 60 days deleting 4 huge returns Using S&P500 for betas There are data points in this estimation before cleaning = 9288.00 elminated observations with unknown fate: 0 Eliminated observations with >100% or <0% shareholder value 36.00 Eliminated observations with missing round date 0 Note. Beta procedure -- cannot handle missing round date, so eliminating those. Eliminating observations that start in second quarter 2000. Need one quarter lag for probability. 57.00 If out date is before or equal to begin date, treat out date as missing. This affects 16.00 Relabeling all ipo, acquisition or new round with zero return as out of business. This affects 14.00 deleting observations with > 300x returns. 3.00 deleting observations with log annualized return greater than 15 2.00 Remaining data: 9190.00 Note: following refers to round, not company. Round may end in another round, though company eventually goes public Percent bankrupt 9.87 Percent ipo 20.62 Percent acquired 24.71 Percent with subsequent round 0 Percent Private 41.24 Percent Ipo registered 3.56 Percent fate unknown 0 0 Percent of bankrupt have good data. Using this parameter in simulation Note: good means round date and exit date not -99 94.49 Percent of new valuation (ipo,acquired,new round) that have good data. Using this parameter in simulation. Note: good means final date not -99, return not missing or 0 49.17 Directional Iteration Func-count f(x) Step-size derivative 1 7 35104.4 0.001 -1.35e+008 2 18 35104.4 1e-011 -1.35e+008 3 26 35104.4 5e-012 -1.35e+008 4 34 35104.4 4.36628e-010 -1.35e+008 5 42 35092.7 8.62935e-008 -1.35e+008 6 53 34700 1.06316e-005 2.88e+004 7 65 34689.6 8.04585e-005 -2.14e+003 8 79 34662.5 0.000835649 2.99e+004 9 91 34387.1 0.00970713 69.4 10 102 34368.5 0.00575043 -1.01 11 113 34092.4 0.112706 1.31e+004 12 124 32705.9 0.0282985 -1.86e+004 13 137 32296.9 0.521252 10.7 14 149 32141.9 0.853427 -0.888 15 160 32113.1 1.02691 0.0116 16 172 32050 10.8383 1.42 17 183 32038.8 1.01185 0.0134 18 195 32036.3 1.49179 -0.00299 19 206 32033.3 1.21906 0.363 20 217 32029 2.95664 -0.207 21 228 32028.6 0.751443 -0.00416 22 239 32028.6 0.56055 -0.000208 Optimization terminated successfully: Current search direction is a descent direction, and magnitude of directional derivative in search direction less than 2*options.TolFun initial and final parameters 0.01 1.50 0.90 0.10 1.00 3.00 0.01 -0.01 1.44 0.53 0.14 0.84 4.31 0.04 chi2 tests.
