When I look at the huge 14% rally today (46.62) the first thing that comes to my mind was a group finance assignment I did with a colleague

After doing a cashflow analysis we had to pick a company that could survive a sudden negative shock to the global system (ie: weather events or recession)

After pouring through the annual report hundreds of times we failed to build a convincing short or bull thesis for James Hardie on the event of a sudden shock (excluding the asbestos liabilities as that is not a global shock)

Nevertheless the group member kept plugging away trying to convince that we should shortlist James Hardie as one that can't survive a shock.

So it is interesting to see what happened today with the results being released and us failing to build a short thesis on James Hardie from a sudden shock to the global system

Perhaps JHX have learnt lessons from building asbestos and are building on those takeaways to grow their business?

Just like Wesfarmers and Promedicus, perhaps another perfect All weather stock?
